Did a quick walk out into DeKorte Park Nature Reserve during lunch, near low tide.
Didn't see any Canvasbacks but did see an extra-secretive Pied-billed Grebe (above) and a Lesser Yellowlegs (left).
The Grebe was distant, and hanging out near the rocks along the distant Saw Mill Creek Trail, which is officially closed.
It tended to hide behind rocks if any humans seemed close, so best to use a spotting scope from the far shore.
Full list follows.
